T 0 (d2 whom 2'25 may concern:

Be itknown that I, Josnrn Rinomcn, a citizen of the United States. and residing at St. Louis. in the State of iilissonri. have in vented certain new and useful Improvements in Lasts, of which the following is a specification. v

This invention relates to lasts and more particularly to lasts of the collapsible type.

The objects of this invention are to construct a last of the collapsible-type provided with locking means for locking the last in extended position, which locking means will be simple in construction. easy to manipulate, and which construction will result in a last having great strength and which is cheap tonnnniiacture.

Further objects will appear from the detail description taken in connection with the accompanying drawing in which:

Figure l is a side elevation 01'' a last in lengthened and locked position, part of the last being in section taken along its l()llgl tudinal center line. Fig. 2' is a viewsimilar to Fig. 1 but showing the last in collapsed position. Fig. 3 is an enlarged detail side elevation of the locking and latching means.

Fig. l is a plan view of Fig. 3,.Fig. 5 is a detail side elevation of a locking and latclring means showing another embodiment of this invention. Fig. i s a pin view of Fig. 5', Fig. 7 is a detail perspective view of a part of the locking and latching means shown in Figs. 1 to l inclusive. and Fig. 8 is a detail of the latching lever.

Referring to the acconi iairving drawing. 10 designates a heel-part and 11 a tore-part of a hinged last of the knuckle joint type. The heel-part and tore-pa t have vertical kerls l9. and 13 cut. in their meeting edges. and these kerts receive a plate l-l. rigidly secured to the heel-part by means of pins 15 and 1t; and pivoted to the tore-part by means ofa pivot pin 17. The tifillstlttt'ftl the art. v

The plate 1!- is cut away on-onc sideso 51 adapted to reeelve one end of a link 3 which pivoted on the pin 16. A link 20 pivoted in the kert l3 on 'a pin 21 in th'. forepart. which pin like "the pins i5. 10 and .7, extends through the last. This link has boss 22510 that its end will snugly fit the nerf 13. The links 1% locked position. In order to unlock t and 20 are pivotally connected by a shouldered pin 23 so as to form a toggle connecting the heel-part and 't'ore-part. lV hen this toggle is straightened the last will be locked in lengthened position and when'the toggle is broken the last can be collapsed. W

The plate 14 is slotted as shown at 2i to receive a latching plate or lever 25 which is pivoted on the pin 1'7. This latchinglevei. is provided with a curved slot 20 having an offset portion 27 and a cam portion The latching lever extends upwardly and is positioned between. the toggle links 19 and 20 with the pin 23 working in the slot 20 and the offset. portion 27. The ends of the pin '23 are riveted over so as to permanently connect the toggle links and the latching lever.

The parts are so constructed that when the last is lengthened the toggle will be straight and the pin 23 will be in the upper end of the slot in the latching lever as shown in Figs. 1. and When the-parts are therefore in the position shown in Figs. 1 and the toggle will lock the last lengthened and the latch will operate to latch the t tile in t. last the latching ever is moved to the left. Figs. 1 and 3 to place the pin 23 in alinement with the slot This movement oil 'the lever will cause the can) portion 28 to engage the pin 23 and more it downwardly sutliciently to break the toggle. The last; can then be collapsed as shown in lf ig. the pin .23 moving downwardly in the slot -(S as the toggle breaks. When the last is again lengthened and the toggle straightened to lock it in lengthened position the lever can he moved to the right, Figs. 1. 2 and 3 to latch the toggle in locked position. In practice the last is lengthened by grasping the forepart and striking the heel-part on the bench. "his will cause the toggle to be rapidly straigjg'htened while the pin 23 in itsoutward movement. will engage the cam 28 and opera -r to autmnaticallv. inovethe lever 25 to the right, .higs. 1. e and 3. to latching posi tion with the oil set portioii 27 in engageinentwith the pin 23. The slot in the latching lever is so constructed that the pin 23 moves freely therein the toggleos broken and straightened. The last maytherefore be lengthened without. manipulating the lev r. and the last will automatically bewas locked when fully lengthened. as de- Ior locking the last in lengthened"position,
